Occurrence of vaccine or drug reactions in bovine carcass

The present study aimed to evaluate the occurrence of abscesses from vaccine or drug reactions in the muscle tissue of bovine carcasses and to establish the location of these abscesses in half-carcasses, in a slaughterhouse located in the northwest of the State of Sao Paulo, under the supervision of the State Inspection Service (SISP). It was possible to identify that 13.50% of the half-carcasses evaluated had vaccine abscesses and of these 91.46% were in the forequarter, 52.50% of these affected the neck, and 27.50% fell. Currently, there is still the presence of abscesses in bovine carcasses from vaccine and drug reactions, which are found in greater proportion in the forequarter, due to the recommendations of this region for the application of vaccines and medications.
